Abstract: A near-eye display and a binocular near-eye display system provide a plurality of different views of an image to different locations within an eye box to impart focus depth cues to a user. The near-eye display includes a multibeam diffraction grating-based display configured to provide the different views and an optical system configured to relay the different views to the different locations within the eye box. The binocular near-eye display system includes a pair of the multibeam diffraction grating-based displays and a binocular optical system configured to provide and relay a stereoscopic image pair representing a three-dimensional (3D) scene to a corresponding pair of laterally displaced eye boxes.

Abstract: A head-tracking multiview display and a system provide a plurality of views of a scene as a multiview image. The plurality of views includes a set of primary views of the scene and a secondary view representing a perspective view of the scene that is angularly adjacent to the primary view set. The display and system are multibeam diffraction grating-based and configured to selectively provide the primary view set and an augmented set of views that includes the secondary view and a subset of the views of the primary view set based on a tracked position of a user or a user's head. At a first position the display is configured to provide the primary view set and at a second position the display is configured to provide the augmented view set.

Abstract: In a supersampling technique, an adjacent pair of pixels in a three-dimensional (3D) electronic display is driven based on angular combinations. In particular, a pixel in the pair is driven by an angular combination of a pixel in a 3D view of a 3D image and at least one product of a pixel in an intermediate 3D view and an associated weight. Moreover, the 3D views applied to the pair have different associated angular ranges with different principal angular directions, and the intermediate 3D view has an associated intermediate angular range with an intermediate principal angular direction that is between the principal angular directions. When viewing the 3D electronic display along a principal angular direction in the principal directions of the 3D view, a viewer sees the 3D view, and when viewing the 3D electronic display along the intermediate principal angular direction, the viewer sees the intermediate 3D view.

Abstract: Polychromatic backlighting employs a grating coupler to diffractively split and redirect collimated light coupled into a light guide. A polychromatic grating-coupled backlight includes a light guide configured to guide light and a light source to provide collimated polychromatic light. The polychromatic grating-coupled backlight further includes the grating coupler diffractively split and redirect to provide a plurality of light beams. Each light beam of the plurality represents a respective different color of the polychromatic light and is configured to propagate within the light guide as guided light at a color-specific, non-zero propagation angle corresponding to the respective different color of polychromatic light. An electronic display includes the polychromatic grating-coupled backlight and further includes a diffraction grating to diffractively couple out a portion of the guided light and a light valve array to modulate the coupled-out light as an electronic display pixel.
